Agricultural water users can optimize water use efficiency and protect the quality of water resources by applying basic information about irrigation systems, crop water use and management practices.

Sensors on the Pivot for Automated Irrigation Scheduling in the Great Plains

Thermal infrared sensors mounted on the center pivot irrigation system for monitoring canopy temperature.
The main barriers to adoption of new technologies in irrigation include cost and ease of use. These scientific methods need to be cost-effective and feasible for farmers to adopt. Today, using soil water monitoring equipment provides the most effective method for farmers to make data-driven irrigation scheduling decisions to apply the minimal amount of water while achieving optimal yields. However, the costs in labor and equipment limit their use. So, research continues to focus on developing lower-cost methods to schedule irrigation that results in putting on just the right amount of water. Since producers do not have time to do detailed work with large amounts of data often generated using SIS methods, the automation of SIS methods would likely provide incentives to producers by saving their time and, simultaneously, reducing the irrigation applications and producing optimal crop yield.

Scheduling the Last Few Irrigations of the Season Deserves More of Your Management Time Than Earlier Irrigations

Nebraska Irrigation Center Pivot
Scheduling the last few irrigations of the season deserves more of your management time than earlier irrigations because one must not only focus on keeping the crop wet enough to produce optimal yields, but also on using up enough of the stored soil water to lower the level to 40% of plant available water in the top four feet. This level will give about 2.4 inches of water storage room in sandy soils and about 5.5 inches in silt loam soils. Unfortunately, many irrigators leave the soil fairly wet with little to no storage room according to a recent study.
